Hi, there I wonder why the eigvecs method does not work for a A::Symmetric{Int64, Matrix{Int64}}. using LinearAlgebra A = SymTridiagonal([1.; 2.; 1.], [2.; 3.]) val3 = eigvals(A)[3] vec3 = reshape(eigvecs(A, [val3]), (:,)) # ✅ this works A * vec3 .- val3 * vec3 # double check the correctness # re-…

Get an eigvec by eigval, using eigvecs, only allow SymTridiagonal?

Ah, yes. But is it efficient? x-ref this.
